A method for managing subscriber load within a terrestrial cellular wireless communication system includes organizing a plurality of cells that form a service area into a plurality of corridors and managing accessibility within each corridor. Each of the plurality of corridors includes a plurality of cells/sectors that have similar loading patterns and that form a contiguous portion of the service coverage area. Periodically, corridor load is determined for each corridor. Further, access rules for the plurality of base stations forming the corridor are determined, these access rules determining which subscribers may access the plurality of base stations forming the corridor. When a loading level for any of the base stations within the corridor-compares unfavorably to a respective loading threshold, access rules for all of the plurality of base stations forming the particular corridor are altered.

6. The method of claim 1 , wherein: the loading thresholds include upper loading thresholds and lower loading thresholds; the subscriber load compares unfavorably to a loading threshold when the subscriber load is greater than an upper loading threshold; and the subscriber load compares unfavorably to a lower threshold when the subscriber load is less than a lower loading threshold.
7. The method of claim 1 , wherein: each of the loading thresholds represents a channel assignment level; and subscriber load represents an assigned channel level.
8. The method of claim 7 , wherein a channel for which the channel assignment level is determined is selected from the group consisting of traffic channels, broadcast channels and control channels.
9. The method of claim 1 , wherein: the loading threshold represents a channel assignment rate; and subscriber load represents a rate at which channels are assigned.
10. The method of claim 1 , wherein: the loading threshold represents a channel assignment acceleration rate; and subscriber load represents an acceleration rate at which channels are assigned.
11. The method of claim 1 , further comprising manually adjusting the loading thresholds based upon planned events.
12. The method of claim 1 , wherein altering the access rules for all of the plurality of base stations forming the particular corridor comprises altering access for particular types of services.
13. The method of claim 12 , wherein: the class of services includes video services; and the class of services supported by the plurality of base stations forming the particular corridor when the subscriber load is less than the loading threshold.
14. The method of claim 12 , wherein: the class of services includes data services; and the class of services supported by the plurality of base stations forming the particular corridor when the subscriber load is less than the loading threshold.
15. The method of claim 12 , wherein the class of services includes non-premium voice services; and the class of services supported by the plurality of base stations forming the particular corridor when the subscriber load is less than the loading threshold.
16. The method of claim 1 , wherein altering the access rules for all of the plurality of base stations forming the particular corridor comprises altering accessibility for a class of subscribers of the wireless communication system.
17. The method of claim 1 , wherein altering access rules for all of the plurality of base stations forming the particular corridor comprises allowing a first class of subscribers to access the plurality of base stations forming the corridor and precluding a second class of subscribers from accessing the plurality of base stations forming the corridor.
18. A method for managing subscriber load within a terrestrial cellular wireless communication system, the method comprising: organizing a plurality of cells that form a service area of the terrestrial cellular wireless communication system into a plurality of corridors, wherein each of the plurality of corridors includes a plurality of cells/sectors that have similar loading patterns and that form a contiguous portion of the service coverage area; periodically, for each corridor: determining a load that is serviced by a plurality of base stations forming the corridor, wherein each of the plurality of base stations corresponds to a cell/sectors of the corridor, based upon the load that is serviced by the plurality of base stations forming the corridor, determining access rules for the plurality of base stations forming the corridor, wherein the access rules determine which subscribers may access the plurality of base stations forming the corridor; and determining loading level thresholds for each of the plurality of base stations forming the corridor and downloading the loading level thresholds to the plurality of base stations; when subscriber load of a base station of a particular corridor compares unfavorably to a respective upper loading threshold, for some of the subscribers that previously had access to the plurality of base stations forming the particular corridor, precluding such access; and when subscriber load of a base station of a particular corridor compares unfavorably to a respective lower loading threshold, for subscribers that previously did not have access to the plurality of base stations forming the particular corridor, allowing such access.
